Hi
I have some questions about rotation that I’m hoping for some help/advice on. The background to my query is that I have a data set derived from a rotating accelerometer (a HOBO pendant G) that lists x-axis, y-axis and z-axis angles recorded every 30 seconds. I can, therefore, easily derive how the each of the three axes has changed over each 30 second period.
However, I’m interested in obtaining a single value of angular rotation over each 30 second period and from the background reading that I’ve done so far, it seems like Rodrigues' rotation formula might be most appropriate. I am not interested in the direction of movement, just a single angle to describe the motion from one position to the next so that I can calculate an angular velocity over each 30 second period.
Is the Rodrigues’ rotation formula most appropriate or could other methods be more appropriately used?
Given my level of maths, the review of Rodrigues’ rotation formula on Wikipedia, does not help me understand how to implement the calculations. Does anyone known of a more straightforward breakdown in any books or on any webpages?
Many thanks for any help/advice offered!
